Specification of Letters Patent.

Patented May 4, 1915.

To all whom it may concern:

Be 1t known that I, FRANK MUELLER, a

.citizen of the United States, residing at Allentown, Lehigh'county,Pennsylvania, have invented certain new and useful Improvements inVHoisting- Gearing for Motor- Trucks, of which the following is a full,clear, and eXact specification.

My invention relates to improvements in hoisting mechanism for motortrucks, and the same has for its object more particularly to provide asimple, eiicient and reliable hoisting mechanism which is operatedthrough, and in combination with the transmission mechanism of thevehicle, and which is also capable of being controlled b the same.operating levers which contro the speed and direction of travel of thevehicle.

, Further said vinvention has for its object to provide a hoistingmechanism adapted to be operated through and in combination with atransmission mechanism of the charactershown and described inUnitedStates Letters Patent No. 954,531, dated March 15, 1910, andgranted to John M. Made, for improvements in transmission mechanism.

Further said invention has for lits-object to provides hoistingmechanism, whichfmay be operated or controlled by the same means whichserves to control the speed or direction of travel of the vehicle insuch amanner that only certain parts of the transmission mechanism maybe operatively connected'with said hoisting mechanism, and at the sametime other parts thereof positively locked against operative connectionwithl said hoisting mechanism.

Further said invention has for its object the provision of additionalmechanism whereby certain portions of the transmission mechanism may' bethrown out 'ofl operation when the truck is notlinmotion and the powergenerated 'by-ithe'femotor transmitted through certain ortionsof themechanism to the-extra sha y in gear-'with a transverse shaft to theends-of which are Y secured the vhoisting drums to receive 'the cable bymeans of which an article may lbe hoisted or lowered. g l A."

Further said invention has for its object to .provide 'a constructionwhereby the vfirst, second and reverse'gears cf the transmission maybedisconneoted from the driving ber-15..' Upon the mechanism of thevehicle, and the motor then used in combination with said first, secondand reverse gears to operate the hoisting mechanism.

Further said invention has for its object to provide a construction inwhich a locking lever is employed to bring the mechanism controlling thefirst, second and reverse gears into operative position to be actuatedby the transmission lever, and at the same time to lock saidtransmission lever against connection with the high speed gear of thetransmission. y

To the attainment of the aforesaid objects and ends, my inventionconsists in the novel details of construction, and in the combination,connection and arrangement of parts hereinafter more fully described,and then pointed out in the claims.

82 denotes a lever which is fixed to a projecting end of the shafty 79and provided at its free end with a handle member 83. The said lever 82is provided intermediate its ends with an offset portion 84.

90 denotes the usual transmission operating shaft which is mounted uponthe forward end of the frame parallel with the shafts 75 and 79, andsupported in bearings 91, 91 arranged upon the longitudinal side membersof the frame. Upon the outer side of one of the frame members is bolteda segment 91 within which is disposed a transmission operating lever 96which is pivotally connected to the shaft 90 so as to oscillate in adirection parallel with the longitudinal axis of said shaft.

92 denotes a sleeve member surrounding the shaft 90 and provided at itsforward end, within the segment, with a supplemental lever 96a, andadjacent to its inner end with an arm 95 which is connected by the link31.* to the forward end of the shifting rod 31a.

93 denotes a second sleeve surrounding the sleeve 92, and provided atits forward end within the segment with a supplemental lever 96" andadjacent to its inner end with an arm 94, which is connected by a link21b with the stud 21a on the tubular shifting rod 21.

The tubular shifting rod 21 controls the low and reverse speeds, and thesolid rod 31, sliding within the tubular rod 21, controls the second andhigh speeds.

The operation of the apparatus is as follows: When the vehicle is inoperation and power is transmitted from the engine to the drivingwheels, the lever 82 is normally in a vertical position, thus permittingthe operating lever 96 to be thrown forward. or rearward within thesegment in connection with the appropriate supplemental'lev ver 96, 96bas may be desired, remembering that the supplemental lever 96 controlsthe second and high-speed through the arm 95, link 31", and rod 31, andthe supplemental lever 96b controlling the low speed and the reversethrough the sleeve 93, arm 94, link 21h and tubular rod 21. It will beunderstood that the lever 82, when in the horizontal or lockingposition, only prevents the high speed gear being connected with thehoisting mechanism and leaves the transmission mechanism free to beconnected to the hoisting mechanism through the low speed, second speedand reverse speed. When the lever 82 is adjusted to its verticalposition, the rod 81 is forced rearwardly and at the saine time thelever 55 given a partial turn to the rear. As this occurs, the gear 53will be released from its engagement with the second speed gear 45, andthus throw the entire hoisting mechanism out of mesh with thetransmission and parts controlled by the driving shaft 11. At the sametime, the clutch member 43 will be caused to engage with the clutch 42under the inlinence of the coil spring 44 arranged upon the jack shaft40 intermediate the secondspeed gear 45, and said clutch member 43; thespring 44 being permitted to restore the clutch member 43 to itsposition in enga ement with the clutch 42 by reason of tne fact that thetoe 58 on the lower end of the shaft 54 has been released of itsengagement with the stud 59a on the lever 59 and thus permit the saidarm 59 to resume its neutral position under the influence of the spring44. At the same time the opposite end of the lever 59, having anenlarged slot or opening, is accorded a. certain amount of forwardmovement without disturbing the neutral position of the clutch 27 uponthe squared portion 32 of the shaft 11. 1n order now yto operate thehoisting mechanism comprising the shaft sections 50, 59, worms 78, 78a,and shaft 75, and drums 77, thereon, it merely becomes necessary to turndown the lever 82 thereby locking the transmission lever 96 against theconnection with the high speed gear. At the saine time that the lever 82is adjusted to its horizontal posi-- tion, the lever 55 will be drawnforwardly and thereby partially rotate the arm 56, and fork 56aconnected thereto and cause the forward end 57 of said fork to shift thegear into engagement with the secondr speed gear 45 arranged upon thejack shaft 40. At the same time the toe 58 on the lower end of the shaft54 will contact with the lng 59a upon the lever 59 and cause one end ofsaid lever 59 embracing the fork 62 to shift the clutch member 43 out ofengagement with the intermediate gear 41 and hold the same out ofengagement and against the tension of the spring 44 upon the jack shaft40. At the same time as the toe 58 engages the lug 59a upon the lever59, the opposite forked end of said lever 59 will Acanise the fork 30 tobe moved slightly to the rearward and at the same time cause the clutch27 to be partly shifted upon the squared portion 32 of the main shaft11, and the clutch member 28 to be withdrawn halfway from its engagementwith the second speed clutch 26, the connection between the two beingfully and operatively maintained. IVith the parts adjusted to thepositions just described, the extra shaft 50, and the hoisting mechanismin gear therewith, will be driven on second speed.

If it is desired to operate the hoisting mechanism on the first speed,it merely becomes necessary to force the tubular rod 21 inwardlyfarther, and cause the fork 2() which embraces the clutch 17, towithdraw the clutch member 18 from its engagement with the reverseclutch 15, and force the clutch member 19 into engagement with the firstspeed clutch 24, whereupon power will be transmitted through the gear29, gear 46, jack shaft 40, and gear 45 to the gear 53 on the extrashaft 50.

If it is desired to operate the hoisting mechanism with the first orreverse speed, the clutch 27 must be adjusted to its neutral positionupon the squared portion 32 of the shaft 11 and the clutch member 28Wholly disengaged from the clutch member 26. Hereupon, the shifting rod21 may be drawn forwardly, and the fork 20 which engages the clutch 17caused to force the clutch member 18 into engagement with the reverseclutch 15, whereupon power is thence transmitted through the gears 14,47, 47, jack shaft 40, gear 45, and gear 53 on the extra shaft 50.
